中文简介:
农业可持续发展的实施需要对植物的生长和发育有新的认识,因为许多“添加剂”的使用是有限的(肥料、农药、植物调节剂……)。为了生产健康食品,我们需要了解特定物种或品种生长发育的生理过程,以及在特定土壤气候条件下使用适当的技术。在水果种植方面,我们将研究不同种类(核桃、苹果、梨)果树(树木结构)的自然发育。这些分析将成为进一步调查的基础(研究初级和次级代谢物,以及树木中激素的状态)。在苹果,我们将研究矿物质对胁迫的影响——光合作用、蒸腾作用、气孔导度、初级代谢物的合成。除此之外,我们还将评估各种果树品种的内在质量,并了解不同环境条件和采用的技术措施对质量的影响。通过对苹果叶片和果实中合成酚类物质的分析,我们将探讨苹果赤霉病的抗性机制,并确定某些品种的抗氧化潜力。在樱桃中,将研究砧木对活力、承载潜力和矿物质代谢的影响。此外,我们将确定生长素在木本植物插条根系形成中的作用,以及在使用某种生长方法时,生长素对核桃和苹果生长发育的重要性。在葡萄栽培方面,我们将对酶活性、抗应激机制以及葡萄藤的适应潜力及其卫生状况进行研究。考虑到“葡萄-土地-技术”综合体对葡萄生产的限制,我们将努力为斯洛文尼亚葡萄栽培中的风土概念奠定基础。在蔬菜种植方面,我们将调查“蔬菜-土壤-环境”循环中营养素的吸收和分布,其中最关注的是最终产品(抗氧化物质)的质量。我们将为添加硒的功能性蔬菜(豆类、土豆、玉米沙拉)的生产创造可能性。此外,我们还将尝试在控制条件下培育选定的蔬菜作物。在植保方面,我们将研究在不使用抗生素的情况下防治火疫病(Erwinia amylovora)的可能性。在实验中,我们将使用proheksadion Ca和阻燃剂。此外,还将研究在Al fosetil和acibenzolar-S-metil(Bion)上制备的药物诱导SAR(系统诱导抗性)的效率。我们将尝试评估它们的有效性、可能引起的副作用,以及对抗微生物物质(酚类化合物)积累的影响。在机械化阶段,我们将确定果实固定在枝条上的力,并可能因物种、品种、砧木、土壤性质(土壤类型、施肥、灌溉)、生长方法、物候期和成熟度而有所不同。将测定水果的机械性能,以改进采收方法、运输和储存。我们将检查玉米遗传物质(群体和品系)对最重要的疾病(镰刀菌属、土枯病菌)的抗性。这将通过在自然条件下对玉米进行人工感染来实现。抗性基因型将用于进一步的育种过程。
课程简介: The implementation of sustainable development in agriculture demands new knowledge on the growth and development of plants as the use of numerous "additives" is limited (fertilizers, pesticides, phyto-regulators ...). In order for us to produce health food, the knowledge on physiological processes of growth and development of a certain species or cultivar is necessary, as well as the use of appropriate technologies in certain pedo-climatic conditions. At Fruit Growing we will study natural development of fruit trees (tree architecture) of various species (walnut, apple, pear). The analyses will then form the basis for further investigations (research into primary and secondary metabolites, and the state of hormones in the trees). In apple we will study the impact of minerals on stress - photosynthesis, transpiration, stomatal conductivity, the synthesis of primary metabolites. Adding to this, we will evaluate the inner quality of fruits of various fruit tree species and find out how the quality varies with regard to different environmental conditions and technological measures applied. With the analysis of synthesized phenolic substances in leaves and fruits of apple we will look into the resistance mechanisms against apple scab and establish anti- oxidative potential of certain cultivars. In cherry the impact of rootstocks on vigour, bearing potential, and metabolism of minerals will be studied. Further, we will determine the role of auxins in the formation of roots of woody plant cuttings and the importance of auxins for the growth and development of walnut and apple when a certain growing method is used. At Viticulture we will perform research into enzymatic activities, resistance mechanisms against stress conditions, and the adaptation potential of vine with its sanitary status. Taking into consideration the limits in the grape production set by the "vine- land- technology" complex, we will try to put down the basis for the concept of terroir in viticulture in Slovenia. At Vegetable Plant Growing we will investigate the absorption and distribution of nutrients in the cycle "vegetable plant- soil- environment" where the highest attention will be paid to the quality of final products (anti-oxidizing substances). We will establish possibilities for the production of functional vegetable with the addition of selenium (bean, potato, corn salad). Additionally, we will try to cultivate selected vegetable plants in- season and out- of- season in control conditions. At Plant Protection we will research into the possibilities for combating fire blight (Erwinia amylovora) without using antibiotics. In the experiment we will use proheksadion-Ca and retardants. The efficiency of SAR (systemic induced resistance) induced with the agents prepared on Al-fosetil and acibenzolar-S-metil (Bion) will also be studied. We will try to evaluate their effectiveness, side effects they may cause, and the impact on the accumulation of anti- microbial substances (phenolic compounds). At Mechanization we will determine the force with which the fruit is fixed to the shoot, and may vary depending on the species, cultivar, rootstock, soil properties (soil type, fertilization, irrigation), growing method, phenophasis, and maturity. The mechanic properties of fruits will be determined in order to improve the harvesting method, transportation and storage. We will examine the resistance of the genetic material of corn (population and line) against the most important diseases (Fusarium spp., Exserohilum turcicum). This wil be carriedd out with artificial infection of corn in natural conditions. The resistant genotypes will be used in further breeding processes.
